Is it possible to convert a phono line to a 3.5mm jack, the same as pc speakers use? An adaptor that takes left and right phono (female) and outputs via a 3.5mm female jack would be perfect. Or is there another option available? ------- q2. A female 3.5mm jack adaptor, female to female. How does the signal direction travel? I'm thinking of using this in an xbox in conjunction with pc speakers.
